For the first time, these 1970s tales are collected in paperback as Swamp Thing encounters a scientist bent on destroying the minds of world leaders, an old-age home whose inhabitants use black magic to regain their youth, and an alien whose voyage across the cosmos has driven him insane. Collects Swamp Thing #14-24, The Brave and the Bold #122 and #176, DC Comics Presents #8, and Challengers of the Unknown #81-87. Includes never-before-collected issues, and the surviving script and art pages from the previously unpublished Swamp Thing #25!
